I’ve never put oatmeal in smoothies before but I’ve seen lots of recipes that do, your pic looks delicious so I’ll have to try it now!

I usually put frozen mixed berries, a frozen banana, greek yogurt (warning, this does make it sour and a lot of people don’t like it but I do haha) and a little bit of milk

Yum! After looking it up, oatmeal is mostly what I use (is “avena” in Spanish), if only because nowadays it’s difficult to get anyone to eat nonfluffy, non whitened cereals.
Also be don’t get berries where I live, when I do, I definitely use cranberries!
My favourite: 1 frozen banana, 6 frozen strawberries, two spoons of oatmeal, half a glass of milk.
My brother’s: a frozen banana, 1 yogurt (greek or probiotic), some brown sugar, cinnamon, 2 ice cubes.
The grossest ever: use an orange or tangerines! It makes the milk separate xD we didn’t know… pity.
